UTC Stamp for Gmail is a Chrome add-on developed by James Furey. It falls under the category of Browsers and specifically belongs to the Add-ons & Tools subcategory. This add-on allows users to insert a muted UTC timestamp at the current cursor position in Gmail.

With UTC Stamp for Gmail, users can easily insert a muted timestamp by simply clicking on the clock icon next to the "Send" button. This timestamp will be inserted at the current cursor position, providing a convenient way to add timestamps to emails.

Furthermore, this add-on ensures that signatures in Gmail are not hidden when a UTC Stamp is appended at the end of the signature. This means that even if you have a signature in your emails, it will still appear in recipient emails without being hidden by Gmail.

UTC Stamp for Gmail is a free add-on available for Chrome users, offering a simple and effective way to add timestamps to emails without any hassle.
